Sir Richard F. Burton, who died at Trieste, Austria, October 30th, was one of the most venturesome travelers and explorers and voluminous authors of modern times. He was born in Hertfordshire, England, in 1821. Having no taste for the university, he entered the East India and afterward the British diplomatic service, he visited the holy places of Arabia and won fame by the book he wrote about them; was the first European to visit Herat; discovered Lake Tanganyika; traveled to Salt Lake City and California; spent three or four years in western Africa; explored the Brazilian highlands and Paraguay; spent two vacations in "unexplored Syria"; visited Iceland; explored the land of Midian; and accompanied Cameron to the Gold Coast. His published works approach eighty volumes, of which thirty-nine are accounts of travel and exploration. Of these the Lake Region of Equatorial Africa is one of the best books on Africa. Burton also published grammars of three Oriental languages, five volumes of folk-lore, three books on fencing, and translations of the Portuguese poet Camoëns, and of the Arabian Nights.

Prof. Thorold Rogers, the eminent English economist, has recently died at Oxford. He was educated at King's College, London, and at Oxford, and began life as a clergyman of the Puseyite school.

He was made Professor of Political Economy at Oxford in 1862, after which he devoted himself mainly to economical subjects, and entered Parliament in 1880. He published two volumes of Historical Sketches; Cobden and Modern Political Opinion; Agriculture and Prices in England (his most important work); Six Centuries of Work and Labor; The Economical Interpretation of History; and the History of Holland in the Story of the Nations series.

Captain John Page, of the Argentine Navy, a summary of whose lecture on the Gran Chaco and its rivers has been published in the Monthly, died in June or July while making an attempt to explore the Pilcomayo River at about one hundred and fifty leagues from its mouth. The expedition reached the mouth of the river in the small steamer General Paz in April last, and Captain Page attempted the ascent thence in a vessel built especially for the service, drawing only eight inches of water; but even then the ascent was found impracticable, and the steamer could often be kept afloat only by damming up the stream.
